SA-T7

tubeLine

Stereo valve preamplifier

Standard, classic circuit technology does not fully exploit the potential of a valve. With the SA-T7 we have developed a preamplifier that raises the pure amplification of valuable music signals to a level never conceived of before with valves. Thanks to the newly developed BestPentode circuit (developed by chartered engineer Frank Blöhbaum), the current distribution noise typical of pentodes is now a thing of the past.

Innovation at a fair price. Developed and produced in Germany.
